Donald Trump attacked Democrats as “un-American” and “treasonous” for failing to applaud him on Monday, only hours after attacking a laundry list of senior figures in the intelligence community as “liars and leakers”.

During a speech at an Ohio factory, the president denounced Democrats who did not clap at his state of the union address, even though partisan applause – and the lack thereof – has become a commonplace ritual of the speech. Republicans rarely clapped for Barack Obama, for instance, as was the case for Democrats listening to George W Bush.
